BS EN IEC 60077-5:2019
This standard BS EN IEC 60077-5:2019 Railway applications. Electric equipment for rolling stock is classified in these ICS categories:
- 45.060.01 Railway rolling stock in general
IEC 60077-5:2019 give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2. The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1 500 V. This document together with IEC 60077-2 states specifically:
a) the characteristics of the fuses;
b) the service conditions with which the fuses comply with reference to:
- operation and behaviour in normal service;
- operation and behaviour in case of short circuit;
- dielectric properties.
c) the tests intended for confirming the compliance of the fuse with the characteristics under the service conditions and the methods adopted for these tests;
d) the information marked on, or given with, the fuse.
This second edition cancels and replaces the first edition, issued in 2003. This edition includes the following main technical changes with regard to the previous edition:
a) test method of test duty III for verification of breaking capacity is reviewed.
